arising before the trabeculee, which are small, yet dis- 

 tinct; antennae short, segment 2 longer than the other 

 segments, segment 5 longer than segments 3 or 4, a few 

 short hairs on the segments; eye distinct, with one very 

 long hair and a short prickle at its posterior angle; 

 temples rounded, with two long marginal hairs and 

 two or three short prickles; occipital margin straight; 

 head of a general dark fulvous, clypeal front paler,

 dorsal spines near the anterior angle, two near the 

 median line, and one nearer the lateral margin; lateral 

 margins with irregular dark borders; intercoxal lines 

 showing through from the under side distinctly, as 

 sharply defined lines, directed in towards the median 

 line, before the posterior margin. Metathorax but little 

 wider than the prothorax, slightly constricted near the 

 anterior angles; posterior angles broadly rounded, with 

 one short hair and one spine; posterior margins nearly 

 straight on the abdomen, except for the acute median 

 angle; a series of long pustulated hairs on the posterior 

 margin each side of the acute angle. Legs pale fuscous 

 without definite markings. 



Abdomen broadly elliptical; angles of segments not 

 projecting, a series of long hairs on the posterior mar- 

 gin of the segments; transverse bands an even, pale
